Hello, I was able to find the author of XML::Twig on perlmonks. Here's the thread about this there: http://www.perlmonks.org/index.pl?node_id=624830

Well, the problem was when I used a copy of the XML::Twig::Elt object. The copy was obtained using: my $copy_of_twig = $twig->copy; where $twig was an XML::Twig object that was used to travese some XML document and at some point needed to be copied. Apparently, the copy operation strips off all the namespace awareness that the original $twig had. I don't know why this makes sense, and how to avoid this. My current workaround is to save a reference to the original twig by: my $ref_to_twig = \$twig; but this just waits to come back and bite me later because as soon as $twig changes its state again, the $ref_to_twig will not "remember" the state from the moment of the referencing, but will do what is expected of a reference to do, and will reference $twig as it changes... Any ideas how to solve this? -- Shlomo Yona [EMAIL PROTECTED] http://yeda.cs.technion.ac.il/~yona/ _______________________________________________ Perl mailing list [email protected] http://perl.org.il/mailman/listinfo/perl
